Influential Factors in Soil Liner Construction for Waste Disposal Facilities

by Jonathan G. Herrmann, US EPA, Cincinnati, OH, USA,

Document Type: Proceeding Paper

Part of: Geotechnical Practice for Waste Disposal '87

Abstract:

Those factors most influential in the construction of a soil liner to meet a permeability performance standard of 1 multiplied by 10-7 centimeters per second (cm/sec) are identified and the rationale for selection is presented. The factors were selected based on a review of the literature on soil liner construction and soil compaction techniques, and through a survey of facility owners and design engineers and a review of post-1984 Part B permit applications for hazardous waste land disposal facilities. Destruction of soil clods and bonding between lifts were identified as basic compaction criteria (most influential factors). Roller type and weight, coverages, lift thickness, and water content were selected as essential choices in achieving the basic compaction criteria.
